While the investigation found that harassment and retaliation were "not pervasive at the network," it also uncovered previous incidents of "improper and unprofessional conduct."

"The company's historical policies, practices and structures have not reflected a high institutional priority on preventing harassment and retaliation," CBS said, citing the probe.

It said investigators found that "inadequate" resources had been allocated to human resources, training and development, diversity and inclusion.

"Employees also cited past incidents in which HR and the company did not hold high performers accountable for their conduct and protect employees from retaliation," CBS added.

But the network said it had already implemented corrective measures, naming a new "chief people officer" responsible for human resources and retaining outside expert advisors "to develop other initiatives for promoting a workplace culture of dignity, transparency, respect and inclusion."

CBS has also seen other harassment claims.

On Friday, it confirmed having paid USD 9.5 million to actress Eliza Dushku, who was written off the script of the series "Bull" after complaining of harassment by the lead actor.
